Dapagliflozin Induced Acute Tubulo-Interstitial Nephritis: A Case Report and Literature Review

We report a case of an elderly male patient, who presented with acute kidney injury on background of diabetic nephropathy, secondary to dapagliflozin induced acute tubulo-interstitial nephritis requiring hemodialysis sessions. Histopathological findings are consistent with moderate tubulo-interstitial inflammation with mixed lymphocytic and eosinophilic inflammatory deposits. The patient responded well to cessation of causative medication and upon initiation of high dose steroids. The direct cause and effect relationship between dapagliflozin initiation and development of acute tubulo-interstitial nephritis is indicative of dapagliflozin being responsible for marked renal deterioration, as seen in this patient.
